< SYMPTOM DIAGNOSIS >[WITH INTELLIGENT KEY SYSTEM]
SQUEAK AND RATTLE TROUBLE DIAGNOSES
Most of these incidents can be repaired by adjusting, se
curing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area c an often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the pos ition the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of thes e incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the \
vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

FRONT OIL SEAL
INSTALLATION
1. Apply multi-purpose grease to the lips of the new front oil seal.
Then drive the new front oil seal in evenly to the gear carrier
using Tool.
CAUTION:
• Do not reuse front oil seal.
• Do not incline the new front oil seal when installing.
• Apply multi-purpose grease to the lips of the new front oil
seal.
2. Install the companion flange to the drive pinion while aligning the matching marks.
3. Apply anti-corrosive oil to the threads of the drive pinion and the seating surface of the new drive pinion lock nut. Then adjust the
drive pinion lock nut tightening torque using Tool (A), and check
the total preload torque using Tool (B).
• The total preload torque should be within the total preloadtorque specification. When not replacing the collapsible
spacer, it should also be equal to the measurement taken dur-
ing removal plus an additional 0.56 N·m (0.06 Kg-m, 5 in-lb).
• If the total preload torque is low, tighten the drive pinion lock
nut in 6.8 N·m (0.69 Kg-m, 5 ft-lb) increments until the total
preload torque is met.
CAUTION:
• Do not reuse drive pinion lock nut.
• Apply anti-corrosive oil to the threads of the drive pinion and the seating surface of the new drive pinion lock nut.
• Adjust the drive pinion lock nut tightening torque to the lower limit first. Do not exceed the drive pinion lock nut
specified torque. Refer to DLN-214, "
Disassembly and Assembly".
• Do not loosen drive pinion lock nu t to adjust the total preload torque. If the drive pinion lock nut
torque or the total preload torque exceeds the sp ecifications, replace the collapsible spacer and
tighten it again to adjust. Refer to DLN-214, "
Disassembly and Assembly".
• After adjustment, rotate drive pinion back and fo rth 2 to 3 times to check for unusual noise, rota-
tion malfunction, and other malfunctions.
4. Installation of the remaining components is in the reverse order of removal. CAUTION:
Check the differential gear oil level after installation. Refer to DLN-207, "
Checking Differential Gear
Oil".

10. Apply anti-corrosive oil to the threads of the drive pinion and the seating surface of the new drive pinion lock nut. Then adjust the
drive pinion lock nut tightening torque using suitable tool (A),
and check the drive pinion bearing preload torque using suitable
tool (B).
CAUTION:
• Do not reuse drive pinion lock nut.
• Apply anti-corrosive oil to th e threads of the drive pinion
and the seating surface of the new drive pinion lock nut.
• Adjust the drive pinion lock nut tightening torque to the
lower limit first. Do not exceed the drive pinion lock nut
specified torque. Refer to " DLN-214, "
Disassembly and
Assembly"
• If the drive pinion bearing preload torque exceeds the
specified value, replace collapsible spacer and tighten it
again to adjust. Do not loo sen drive pinion lock nut to
adjust the drive pinion bearing preload torque.
• After adjustment, rotate dri ve pinion back and forth 2 to 3
times to check for unusual no ise, rotation malfunction,
and other malfunctions.
11. Check companion flange runout. Refer to DLN-231, "
Inspection and Adjustment".
12. Install the differential case assembly. Refer to DLN-214, "
Disassembly and Assembly".
Differential Assembly
1. Install side gear thrust washers with the same thickness as the ones installed prior to disassembly, or reinstall the old ones on
the side gears.
2. Install the side gears and side gear thrust washers into the dif- ferential case.
3. Install the pinion mate thrust washers to the two pinion mate gears. Then install the pinion mate gears with the pinion mate
thrust washers by aligning them in diagonally opposite positions
and rotating them into the differential case.Drive pinion bearing preload torque:
2.3 - 3.4 N·m (24 - 34 kg-cm, 21 - 30 in-lb)
